Description:
|
When we were using "Dynamic Choice Parameter (Scriptler)", we found something is not right.We wanted to run a script, which would import classes of svnkit, to get a list of pathes in svn.
The script was as follow:
import java.util.*
import org.tmatesoft.svn.core.ISVNDirEntryHandler
import org.tmatesoft.svn.core.SVNDirEntry
import org.tmatesoft.svn.core.SVNNodeKind
import org.tmatesoft.svn.core.SVNException
class SVNDirEntryHandlerImpl implements ISVNDirEntryHandler {
List<SVNDirEntry> dirs = new ArrayList<SVNDirEntry>()
void handleDirEntry(SVNDirEntry dirEntry) throws SVNException {
dirs.add(dirEntry)
}
}
def h = new SVNDirEntryHandlerImpl()
def result = []
h.dirs.each() {
def dirName = it.name
if (null != dirName && dirName.length() > 0 && SVNNodeKind.DIR == it.kind) {
result.add(dirName)
}
result.add(dirName)
}
return result
The script was run well in Scriptler, but we got an empty list in job build parameter, without any errors.We read the log of tomcat, and we found "unable to resolve class" error.
Log was as follow:
2013-7-29 10:37:34 com.seitenbau.jenkins.plugins.dynamicparameter.BaseParameterDefinition executeScript

After reading the code of "Jenkins Dynamic Parameter Plug-in"(TAG 0.2.0), "Scriptler Plugin" and Groovy, we found the reason of this error.
The code of function execute(String script, Map<String, String> parameters) in class com.seitenbau.jenkins.plugins.dynamicparameter.util.JenkinsUtils is as follow:
public static Object execute(String script, Map<String, String> parameters)
{
CompilerConfiguration config = new CompilerConfiguration();
GroovyShell groovyShell = new GroovyShell(config);
for (Entry<String, String> parameter : parameters.entrySet())
{
groovyShell.setVariable(parameter.getKey(), parameter.getValue());
}
Object evaluate = groovyShell.evaluate(script);
return evaluate;
}
Here, groovyShell use the constructor GroovyShell(CompilerConfiguration config), so Groovy use the class loader of GroovyShell as the parent class loader of Groovy. The class GroovyShell is loaded by Jenkins(You can find the jars of goorvy in webapps\jenkins\WEB-INF\lib). The class loader of GroovyShell is same to Jenkins. The classes of svnkit are loaded by subversion plugin(You can find the jars of svnkit in the path of subversion plugin). The class loader of svnkit classes is same to subversion plugin. According to document of Jenkins, the class loader of plugin extends the class loader of Jenkins, so the class loader of Groovy can not find the classes of svnkit.
We sugget that modify the function execute(String script, Map<String, String> parameters) to follow:
public static Object execute(String script, Map<String, String> parameters)
{
GroovyShell groovyShell = new GroovyShell(Thread.currentThread().getContextClassLoader());
for (Entry<String, String> parameter : parameters.entrySet())
{
groovyShell.setVariable(parameter.getKey(), parameter.getValue());
}
Object evaluate = groovyShell.evaluate(script);
return evaluate;
}
Then Groovy will use the context class loader of current thread as the parent class loader, and Groovy can find the classes of svnkit.
We test this code in Jenkins, the script run well, and we get the list which we want.
